Super Simple Halloween Slime Recipe

I’ve been making this slime recipe for years. It was always a favorite with my elementary students. The slime recipe is really simple and almost always works perfectly. There a ton of different slime recipes out there currently and to be honest I haven’t tried any of them. I like our space slime and valentine’s glitter slime. So today I’m sharing a Halloween version.

Safety note: Always supervise the making and playing of slime. Once finished wash your hands to get rid of any residue (glue and liquid starch can dry skin). Slime should only be used with kids that won’t eat it. While the ingredients I use (glue and liquid starch) are technically non-toxic and safe for everyone to handle, I don’t think it’s good practice to allow kids to eat it. Too much could cause an upset stomach. Other slime recipes have different ingredients so be sure you understand the safety requirements before using those. For a taste safe version of slime, try making oobleck.

Supplies You’ll Need:

  • Elmer’s washable clear glue
  • Liquid starch (find this in the laundry aisle)
  • Washable liquid watercolors (you can also use food coloring but food coloring can stain)
  • Water (technically optional but it will make things easier)

Many of the slime recipes add water to their glue. I wasn’t sure why this was done. In fact, it’s not actually necessary. Combining glue and liquid starch in about equal amounts will give you great slime every time. The exact amounts vary depending on humidity and other environmental factors, but a 1:1 ratio of glue to liquid starch is always a good place to start.

The biggest problem with using just glue and liquid starch is that it often requires a lot of kneading. Then, you add more liquid starch until the slime is no longer sticky. Adding just a little bit of water to your glue fixes this problem. The slime comes together much easier and requires less kneading.

I like to make individual batches of slime – this is perfect for kids to each make their own. Mix the ingredients in plastic cups with craft sticks to make clean up super easy.

Here’s the individual slime recipe I use:

1/4 cup clear glue (about half a small bottle)
1 tablespoon water
few drops of washable liquid watercolors
about 1/4 cup liquid starch (don’t add it all at once, you might not need it all)

Watch the video to see how easily the Halloween slime comes together.

How To Make Halloween Slime

  1. Add 1 tablespoon of water to a 1/4 cup of clear glue.
  2. Stir in a few drops of washable liquid watercolors (or food coloring) to get the color you desire.
  3. Add in a little less than a 1/4 cup of liquid starch. Stir. Go ahead and knead the slime with your hands. If the slime is stringy and sticky, you’ll need to add more liquid starch. Keep kneading until the slime feels right. If it happens to be stringy and super slippery, you may have added too much liquid starch.
